Mineral recovery system for a Closed Ecology Experiment Facility (CEEF).

Life support & biosphere science : international journal of earth space, 1999
A unique recovery system, which consists of electrodialysis (ED) and crystallization processes, is proposed for NaCl (salt) from waste water after oxidation of urine. NaCl recovery characteristics from the oxidized urine, which contains KCl and NO3- impurities, were experimentally evaluated.

Water cycles in closed ecological systems: effects of atmospheric pressure.

Life support & biosphere science : international journal of earth space, 2003
In bioregenerative life support systems that use plants to generate food and oxygen, the largest mass flux between the plants and their surrounding environment will be water. This water cycle is a consequence of the continuous change of state (evaporation-condensation) from liquid to gas through the process of transpiration and the need to transfer ...

Optimum control of closed ecological systems: mathematical aspects.

Life support & biosphere science : international journal of earth space, 1999
Optimum control of a closed ecological system (CES) is not possible without adequate CES description and appropriate evaluation of factors, which act upon the system and introduce additional errors and uncertainties into the forecast of the CES state. The statement about key significance of stationary state consideration for further CES development is ...
